Although it kind of makes for an unprovable assertion, isn't there a
possibility of stealth here? Would Jupiter brains or your Ouranos quark
brains want to call attention to themselves?

Also, I'm not sure how clear the Hubble data are. From my reading, the
globular clusters don't currently have detectable planetary disks. That
doesn't mean they didn't have them or that they don't have them below
detectable levels. Add in stealthing and -- well, add it in and you can
pretty conceive of any possible reason not to get a peek at Jupiter brain
